Detailing Richlandís Dual Graphics & GCN Compatibility (Comment Thread)
Considering their architectural differences, AMD's VLIW4-based Richland APUs and the Sea Islands' HD 8000M series may seem like strange bedfellows. However, AMD has somehow allowed them to work together in Dual Graphics mode in order to enhance graphics performance.

I'm still waiting for that day when CPU power is increased by 40% instead of the graphics.
Unfortunately, changing an architectural direction isn't easy. Piledriver and Steamroller don't feature support for legacy instruction sets which means they suffer in some of today's most utilized programs. Had those instruction sets been retained, we would be facing a very different scenario.
Moving away from this approach will likely take years.
This translates over to the desktop side, as the less power consumed by a chip, the less heat output, and the quieter the PC.
Case in Point, for all intents and purposes, the 8350 matches the 3570K in gaming performance (it's a little lower, but not by a whole lot). However it uses almost three times as much power, and outputs that much more heat. The cooling solution attached to that chip has to work three times as hard to keep the chip cool, therefore creating more noise.
Back to the mobile and APU side, if AMD can combine decent CPU processing power, and mid-level graphics power on one chip, while keeping powerconsumption and heat output low, they'll have a real winner on their hands. I think they're well on their way in that respect.
Until more programs utilize the extra cores AMD offers over Intel in their mid range mobile processors I still feel Intel will continue to be a winner unless AMD can step up in the CPU game. Intel is definitely stepping up their graphics game and I feel AMD will have to step up their CPU power to keep up while maintaining a good performance per watt ratio.
